I just upgraded my phone and restored from a backup. When I first launched OF2 it ran okay and I just switched it to ‘dark’ mode and quit the app.
Now it crashes within seconds of opening, I can see that it is trying to sync but nothing more than that. I’ve tried restarting the phone etc.
Unfortunately I can’t upgrade to OF3, because I’m still running OF2 on my iMac, as I am still on El Capitan due to other programs.
